Description:Current issues are now on the Chicago Journals website. Read the latest issue.The International Journal of Plant Sciences has a distinguished history of publishing research in the plant sciences since 1875. IJPS presents high quality, original, peer-reviewed research from laboratories around the world in all areas of the plant sciences. Topics covered range from genetics and genomics, developmental and cell biology, biochemistry and physiology, to morphology and anatomy, systematics, evolution, paleobotany, plant-microbe interactions, and ecology. IJPS does NOT publish papers on agriculture or crop improvement. In addition to full-length research papers, IJPS publishes review articles, including the open access Coulter Reviews, rapid communications, and perspectives. IJPS welcomes contributions that present evaluations and new perspectives on areas of current interest in plant biology. IJPS publishes nine issues per year and regularly features special issues on topics of particular interest, including new and exciting research originally presented at major botanical conferences.

There are no costs for publishing in IJPS. The journal does not assess page charges, and color figures that enhance the quality of papers are provided free of charge. Manuscript evaluation times vary, but decisions on peer-reviewed papers typically take 5–6 weeks.

The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

Scanning electron microscopy of thick hand sections of the giant thick-stemmed grasses Arundo donax and Phyllostachys aurea was used to see how the primary xylem of a monocot with pronounced basal meristem activity in stems differs from xylem in monocots that show gradual elongation in stems. Several intact protoxylem vessels with annular thickenings can be simultaneously present in a single bundle, indicating that redundancy is a possible mechanism for countering loss of integrity resulting from elongation stress. Protoxylem vessels can be large in diameter, even larger than adjacent metaxylem vessels. There is little or no network of cellulosic fibrils in the primary walls (including end walls before dissolution) of protoxylem vessels, suggesting that primary walls are essentially gelatinous and therefore may elongate more readily than other vessel elements studied to date. Annular vessels are much more common than helical ones. Other notable structural features reported are smoothness of the inside of primary walls in protoxylem vessels, absence of borders on annuli or gyres of protoxylem vessels (but presence of borders on rims of perforation plates), and grooves interconnecting one to 10 pit apertures (coalescent pit apertures) on the inside surfaces of metaxylem vessels. Use of thick sections for study with scanning electron microscopy permits imaging that is ideal for understanding three-dimensional aspects of xylem anatomy and is recommended over the study of thin sections.
